Answer:
Option A
Step-by-step explanation:
We need to find two expressions that, when simplified, give the same results.
1) First, simplify the expression stated in the question. Multiply each of the terms in the parentheses by the number that is next to them. This would mean you have to multiply both 9x and -6 by
. You also have to multiply
and
by 4. Then, simplify.

2) Now, combine the like terms.


So, we need to find which of the expressions listed equal 8x - 6.
3) Let's try option A. Do the same as before. Multiply each of the terms in the parentheses by the number that is next to them. So, multiply 4x and -12 by
. Also, multiply 30x and 18 by
. Then, combine like terms and simplify.

This also equals 8x - 6. Therefore, option A is the answer.
( 'x' is not 144 .)
The supplement of an angle is (180 - x) .
The problem says that (2/3) of 'x' is equal to (180 - x) .
180 - x = 2/3 x
Multiply each side by 3 :
( Note: 3 x 180 = 540 .)
540 - 3x = 2x
Add 3x to each side:
540 = 5x
Divide each side by 5 :
<u>x = 108°</u> .
Answer:
$2 per ride
Step-by-step explanation:
$32-$20=$12
McKenna rode 6 rides so $12 divided by 6 rides is $2 for every ride

The given statement can be represented as :
where, the number is assumed to be " b "
therefore, the correct choice is B. 2b³ - b
